If you weren’t able to make it but still interested in the potential role native plasmids play within Sphingomonas-plant interactions. Can check it out now on Zenodo zenodo.org/records/1591...
![A hyperactive ACD6 allele reduces growth and causes necrosis only in the greenhouse. Top: Representative Arabidopsis thaliana rosettes from different genetic backgrounds. Yellow and blue labels represent descendants of a heterozygous ACD6 HIF line that are homozygous for either the Est-1 or the Col-0 allele of ACD6. Green and purple labels represent the Est-1 accession and the isogenic acd6 knockout null allele in that accession. Plants were grown in Tübingen in the greenhouse (GH-Tü), outdoors in the field in Tübingen (F-Tü), or outdoors in the field in Zurich (F-Z, a GMO-approved facility).

Bottom: Rosette size of individual plants, calculated by quantifying green pixels from images similar to those in the top panel. The line within each box represents the median. Boxes enclose the interquartile range (IQR) with whiskers extending to up to 1.5 times the IQR. Brackets indicate Mann–Whitney U-test results, with * indicating P < 0.05 after Benjamini–Hochberg correction for multiple testing across the four comparisons. Dotted lines extending from the mean of each distribution span the observed effect size, and a bootstrapped distribution of computed effect sizes [30] is shown in gray, centered on the mean of the second box in each pair (red dot). The black bar extending vertically from the red dot represents the 95% confidence interval of the effect size.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:5522ztebtekoor5efelihqhb/bafkreiaqunadge3nltwergaw3byzldjmd7k2prjfsz7tfv4ycecjvwxmtm@jpeg)

In the greenhouse, #Arabidopsis with hyperactive ACD6 have stronger pathogen defenses but are smaller & make fewer seeds. @derekseveri.bsky.social @plantevolution.bsky.social &co show that in the open field both advantages & disadvantages of the allele disappear @plosbiology.org 🧪 plos.io/465XPDR

This work started nearly 10 years ago and was once my main postdoctoral project at @plantevolution.bsky.social before I slowed work on it to a trickle because it became confusing. But it always remained extremely interesting.

Thanks a lot! ☺️

Last week, I had a great time at the New Phytologist EiC Symposium: “Microbes as hidden or prominent players in plant life” in Tartu, Estonia!
Honored and very happy to receive the Best Poster Award! ✨
Big thanks to the organizers and all the inspiring scientists I met! 🌱 @newphyt.bsky.social
